Please always answer to the google group. Right now there is no way of inspecting properties + types.
The only thing I can imagine is to set a "sample" of actual properties on the meta-nodes created from the actual nodes. But it will slow down the whole meta-graph creation: It is much easier to write a client program that inspects the graph and creates the meta-graph correctly probably not even in Neo4j itself. By using endpoints like: "node_labels" : "http://localhost:7474/db/data/labels";, "relationship_types" : "http://localhost:7474/db/data/relationship/types";, http://localhost:7474/db/data/propertykeys MATCH (a)-[r]->(b) WITH labels(a) AS a_labels,type(r) AS rel_type,labels(b) AS b_labels,a,b,r UNWIND a_labels as l UNWIND b_labels as l2 MERGE (meta_a:Node:Meta {name:l}) SET meta_a += a MERGE (meta_b:Node:Meta {name:l2}) SET meta_b += b MERGE (meta_a)-[:OUTGOING]->(meta_r:Relationship:Meta {name:rel_type})-[:INCOMING]->(meta_b) SET meta_r += r MATCH (m:Meta)-[r]-() RETURN m,r On Tue, Nov 18, 2014 at 11:39 AM, Marwa Elabri <[email protected]> wrote: > Good morning > thank you for your answer.
